Two fabrication schemes of magnetic metal-polymer nanocomposites films are described. The nanocomposites are made of graphene-coated cobalt nanoparticles embedded in a polystyrene matrix. Scheme 1 uses non-covalent chemistry while scheme 2 involves covalent bonding with radicals. Preservation of the net-moment of cobalt and electrical insulation are achieved by means of a core double-shell stru...

The use of nanostructured materials and nanosized-topographies has the potential to impact performance implantable biodevices, including neural interfaces, enhancing their sensitivity selectivity, while reducing tissue reactivity. As a result, current trends in biosensor technology require effective ability improve devices with controlled nanostructures. Nanoimprint lithography pattern surfaces...

Polystyrene and polystyrene copolymers have many unique properties that make them desirable for use in flexible packaging. Polystyrene monofilms however are not practical for use on high-speed packaging lines due to their poor heat sealability and flex cracking. Coextruded films of polystyrene with polyethylene combine the desirable properties of polystyrene with polyethylene. Still, PS coextru...

The preparation and characterization of high-surface-area polymeric substrates suitable for the microcalorimetry of protein adsorption are described. High-surface-area polystyrene, poly(styrene-co-butyl methacrylate) and poly(styrene-co-allyl alcohol) were prepared by adsorbing polymer from solution onto fumed silica. Verification of adsorption of polystyrene by silica was determined by noting ...
